TSED70Q TS Imaging Star 70mm f / 6.78 ED Quadruplet Flatfield APO Refractor

TS 70mm f / 6.78 QUADRUPLET ED Flatfield APO Refractor with a focal length of 474mm.
A 4-element ED refractor with built-in field correction for astrophotography and observation

The TS Quadruplet ED Astrograph is an ideal travel telescope for all photographers. The apo is very well corrected by the built-in corrector on the axis and in the field. Even cameras with full-size sensors can be used. In addition, the APO also provides a decent visual performance. Magnifications up to approx. 150 times are handled by the ED lens well, the color error is significantly reduced.

The ED Quadruplet is a recommendation for all nature observers, photographers and amateur astronomers who are looking for a compact telescope and spectra for the road, which fulfills all tasks very well. The overall length of only approx. 30cm (with retracted cover cap) makes the Apo a real transport miracle.

TSED70Q TS ImagingStar 70 / 474mm ED APO

The advantages of the TS 70mm Quadruplet:

- very good field correction by built-in 2-element field rector
- simple adaptation of the camera or eyepiece without tedious distance search
- 2 "dual speed Crayford extract allows photography and observation
- 360 ° rotation of the pull-out for the correct image cut-out
- flexible multi-function connection plate for direct attachment to photostats and easy adaptation to mountings
- Well-corrected duplex lens with two special lenses (1x lanthanum) for a clear contrast-rich image

The 2 "Crayford eyepiece extractor with 1:10 microcompression:

The 2 "Crayford pullout also keeps heavy accessories bomb-resistant by means of reinforced ball bearings.It guarantees a very precise adjustment by the 1:10 micro-adjustment.If you have adjusted the sharpness exactly, you can fix the position with a thumbscrew, thus long exposure times are possible Without the sharpness changing.

Taking pictures with the TS 70mm Quadruplet:

Simply connect your DSLR or CCD camera via our 2 "focal adapter (TSFA2) or via the M48 screw adapter (TSFOC-M48), focus on the best possible photographic performance.

The necessary adapters can be found in the accessories section.

Watching with the TS 70mm Quadruplet:

The Apo is optimized for photography, but it also offers a very good performance for the visual observation with 1.25 "accessories. The focus position allows the use of 1.25" zenith mirrors or Amici prisms for erecting the image.

They reach e.g. With the TS 32mm Super Plössl a gigantic field of 3.5 ° at only 14x magnification. This gives you an optimal overview. With our HR3 Planetary Eyepiece, you get 148x magnification and can observe details on the moon and planets very well.
